TH READ-GUARD FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 252,814, datedJanuary-24, 1882.

Application filed August 25, 1881.

T 0 all whom it may concern:

Be it known that I, EDWARD S. STIMPSON, of Hopedale, Worcester county,State of Massachusetts, have invented an Improvement in Thread Guardsfor Spinning Machines, of which the following description, in connectionwith the accompanying drawings, is a specification.

This invention relates to threadguards to be placed between the adjacentrings ofringspinning machines to prevent the yarn being spun and woundupon adjacent bobbins from striking together and being broken.

My improved guard is composed of a plate of metal having a foot extendedlaterally or at right angles therefrom, and provided with a hole toreceive a screw, which is inserted loosely through the said foot into athreaded hole in a block or slide of substantially the same size as thefoot, the said foot and slide having between them proper spaces andbeing of proper shape to embrace and be clamped to two parallel rodsextended along the frame longitudinally from end to end, so that theseries of guards thereon may be readily and easily adjusted horizontallyupon the said rods and be quickly clamped in any desired position by themanipulation of the screws in the feet of the guards. The employment ofthe two rods to receive the feet and blocks of the guards obviatesmaking screw-holes or screwseats, as is common when a single rod isemployed.

Figure 1 represents in front elevation a sufficient portion ofaring-spinning frame to illustrate my invention; Fig. 2, a sectionthereof on the dotted line no 00 of Fig. 1, looking toward the left;Fig. 3, a section on the dotted line y y of Fig. 1, and Fig. 4 anenlarged view of one of the blocks at the end of the series of guards toshow its pin.

The bar a, a fixed part of any usual ringspinning frame-preferably apart of the roller-bea1n-has connected with it at each end a suitablehanger, b, providedat its lower end with a hole to receive a pin,vc, ofthe block (I, which co-operates with the foot e of the endmost guard, 0of the series of guards, four only being shown. The foot of each guardreceives loosely a screw, f, which is inserted into a threaded part ofthe block 61, which co-oper- (No model.)

ates with the foot, the foot and block being placed at opposite sides oftwo parallel rods, 9 it, so that turning the said screw in will clampthe said foot and block upon the said rods in any desired position andhold them there with the guard e in the proper position with relation tothe rings k in the rails m and the spindles l and bobbins a, the upperends only of which are shown in Fig. 1. Each hanger b will have afinger, N, to serve as a rest or support (see Fig. 2) for the lowermostrod, h, thus keeping the guards extended horizontally, or nearly so,forward between the rings and spindles.

I do not broadly claim a thread guard, as I am aware of United StatesPatent No.202,420, wherein a single rod is used to support the guard, ascrew impinging against said iod to hold each guard in place laterallyand horizontally.

By employing two parallel rods or bars upon which the feet of the guardscan take seat, as shown, the said'feet are made instrumental inpreventing the guards turning vertically with relation to their support.

I claim- 1. The hangers adapted to be secured to the frame of themachine, and the two parallel rods or bars g h, combined with a seriesof guards having feet, and with blocks and screws to clamp and hold I118said feet in adjusted position on the said rods or bars, substantiallyas described.

2. The guard e and its laterally-projectiug foot 0, provided with ahole, and the block (I, provided with a threaded hole, and the two rods9 h, placed between them, combined with the screwf, inserted looselythrough the feet and screwed into the block, subst ntially as described.

3. The hanger I), provided with the finger 0 combined with the rods 1 h,block 61, and its pin 0, and with the guard and its foot and screw, allsubstantially as described.

In testimony whereofl have signed my name to this specification in thepresence of two subscribing witnesses.

EDWARD S. STIMPSON.
